Abstract

In response to global warming, the International Maritime Organisation (IMO ) se t rule s of 50 % Greenhouse Gas (GHG ) reduction by 2050, from 2008 levels. Signatory countries to the IMO' s regulation require frequent assessment of the contribution of GHG emissions from shipping calling at their port s or trading in their territorial waters to ensure their compliance with the regulations. This demand s a rapid an d accurate method to assess ship - ping's contribution to GHG emissions. Current methodologies for estimating emission s from ship s ca n be describe d on a scale between bottom -up and top - down methods. Top - down method s provide rapid estimates primarily based on fuel sales reports without considering individual vessel details. Therefore , they are less accurate and do not provide a breakdown of emission s by ship type s or in specific regions. Bottom - up methodologies are detailed vessel based estimates; however , they are data and time demanding. The Ship Emission s Assessment method (SEA ) (Topic et al., 2021 ) fills the gap between bottom - up and top - down method s by providing an innovative hybrid solution for rapid but accurate ship emission estimation . It uses publicly available , cost -effective data sets for emission estimates. The SE A method is capable of estimating ships' emission s in designated areas to understand regulations' effectiveness and provide emission quantification evidence. This research objective was to apply the SE A method to quantify CO₂ , SOx an d NOx exhaust emission s from containerships for the three crucial containership ports: Trieste , Rijeka an d Venice , in the North of the Adriatic Sea. Th e SEA methodology was applied to assess emissions and forecast efficiency in scenarios of different regulatory measures. A reduction in NO x emission s was estimate d for the even t of the implementation of NECA in all three ports. Result s showed that 447.13 tonnes of NO x could be reduce d each year in the North Adriatic Se a area around the ports of Rijeka , Trieste an d Venice in the even t that NECA regulations are stipulated.
